I have back pain for last 2 and 1/2 months. Pain is in middle and upper middle of back. Earlier also I have back pain on and off. Sometimes after 2-3 months and sometimes after 6-9 months and so on but the same was vanished after 3-4 days. This time it is not so. This may be due to long sitting on chair (from 10 to 6). I have taken 1 week physiotherapy (ift) and also taking vitamin d3 and calcium tablets. I have taken homeopathy spondy aid (backsons). Some relief is there but not fully. Do you suggest some homeopathy drops and homeopathy tablets.
